How It Works

This tool uses military-grade encryption entirely in your browser:

🔒 AES-256-GCM

Advanced Encryption Standard with 256-bit key and Galois/Counter Mode for authenticated encryption

🔑 PBKDF2

Password-Based Key Derivation Function with 100,000 iterations to protect against brute-force attacks

🎲 Random Salt & IV

Unique cryptographic random values for each encryption ensure identical texts produce different outputs

💻 Client-Side

All encryption happens in your browser using Web Crypto API. Nothing is ever sent to any server

Encoding and Data Utilities

Encode, decode, measure sizes, and transform common formats.
